The traditional heating method of single-sided heat press machine is steam heating and electric heating. Steam heating quickly heats up, but a pressure boiler is required. The pipeline pressure is high. Steam easily condenses into water, causing uneven surface temperature; the temperature of electric heating rises quickly. , The heating temperature is high, the control is simple, but the power consumption is high, the working cost is high, and the shortcomings of the resistance wire in the specific use are difficult to replace.

Therefore, when the single-sided hot press is used in the furniture industry, the hot-water circulation furnace can also achieve satisfactory results when the hot-pressing temperature is not high, and the fixed investment and operating costs are very low. The hot plate of a single-sided hot press is generally made of a whole piece of constrained steel plate through deep hole drilling, which can prevent oil leakage caused by poor sealing.

The hot plate of the single-sided hot press has higher rigidity and strength, but the hot plate is thicker and heavier. Since thin plates are usually used, stresses are generated during welding and processing, so higher processing accuracy is required. The thin heating plate is easy to preheat and control the temperature, but the requirements for the processed parts are very high. Uneven thickness of the workpiece will cause deformation of the pressing plate, which will affect the quality of subsequent processing.

When manufacturing and processing a single-sided hot press, please ensure that the flatness of the hot press plate and the upper and lower surfaces have sufficient parallelism. The flatness tolerance of the hot pressing plate should be within the range of 0.1-0.18mm, the parallelism tolerance should be within the range of 0.15-027mm, and the surface roughness of the pressing plate should be 3.2μm. The temperature difference across the entire width of the heating plate should not exceed 2-3°C, so as not to affect the strength and appearance quality of the product.

The connecting pipe of the heating plate of the single-sided hot press is basically a hose, so the connection is very convenient. Both metal hoses and polytetrafluoroethylene hoses can be connected by flanges, and the fatigue resistance of polytetrafluoroethylene hoses is better than that of metal hoses. Sealing materials such as polytetrafluoroethylene, coiled graphite, etc. have a better sealing effect.
